| Abstract: | In the paper, the passing vibration is effectively detected with wavelet transform and the passing frequency in time domain is estimated. The passing vibration is caused by defect in some elements of rotating machine such as shaft bearing,etc., and it is usually difficult to identify. The method offered provides useful means for machinery fault diagnosing. |
